a heel portion adjoining the junction With the shaft, and means forattachment to the sh'aft, said sole and top being curved to meet andform a sharp peripheral trailing edge which extends from the toe of thestriking face and around the rear of the head to the heel portion.

3. In a socket or scared golf club, a head provided With afront-striking face, a curved sole to said head, a convex top to saidheadl` and means carried by the head for attachment to the shaft, saidsole and convex top being curved to meet and form a sharp' peripheraltrailing edge which extends around the rear of the head, `and saidcurved sole bein'gformed as a continuous convex sur? face having itscentre in the pivotal axis of the golfefs swing. i

4. In a socket or scared golf club a shaft, a headl provided with afront striking face, a sole which is curved from front to rear of thehead 'and curved also from the toe to- Wards the shaft of the club, aconvex top and means for attachment to the sliaft, said sole and convextop 'being curved to meet reeaaee curved sole being formed ofspoon-shape' with its Ilowest portion curved conntric with the golfersswing, this lowermost portion being 'Curved fore and aft more sharplyupwards. z.

In a socket or scared 'golf club, 'a head provided with a front face, a.curved sole, a convex top and means for attachment to the shaft, saidsole and convex top being continuously curved to meet and form asharptrailingedge which extends around the rear of thehead, and said curvedsole having its centrein the pivotal' axis of the golfer7s Swing, astriking plate secured upon the front face of the head, and a weightinserted in said head behind saidstriking plate, 'a line from the reartrailing edge to the centre of the height of said front plate passin'gthrou h said weight.

l6. n a socket or scared golf club, a head provided with a frontstriking face, a curved sole, a convex top and means, for attachment tothe shaft, said sole and convex top being curved to meet and form asharp trailing edge which extends around the rear of the head, and saidourved sole having its centre in the pivotal axis of the golfe-r7sswing, a striking plate secured upon the front face of the head, and aweight inserted in said head behind said striking plate, a line' fromthe rear trailing edge to the centre of the height of said strikingplate passing through said weight, said Weightv being V'composed of ametal cylinder with its axis' at right angles to the front plate. i

`7. A golf club com'prising a sha-ft, a head, a connection between saidshaft and head, an obliquel)7 cut front to said head, a striking' platesunk in said front, acontinuously curved sole and a` convex top, saidsole and convex top being streamlined rea-rwardly to form a sharpperipheral trailing edge, and said convex sole being of spoon-shape.

In testimony whereof I afi'ix mysignature.

and form a sharp trailing edge which extends around the rear of thehead, and said ROBERT MoKENZIE.
